You are solving a spreadsheet benchmark task in a real workbook. Objective: Produce the correct final workbook state for the expected answer region. What matters: - Only the values in the expected answer region will be graded. - The workbook is the answer. Instructions: 1. Read the workbook and inspect the relevant data region first. 2. Infer the required result for the provided workbook instance. 3. Write the final value(s) directly into the expected answer region. 4. Do not rely on prose, formulas in your chat response, pseudocode, or VBA as the answer unless the benchmark explicitly requires those to be written into cells. 5. If the natural-language task asks for a general method, formula, or macro, convert that into the concrete result needed for this workbook instance. 6. Keep your final text response short and only summarize the workbook cells you changed. Relevant data region(s): A1:J1000 Expected answer region(s): G1:I1000 Expected answer sheet(s): merge Task: How can I create my Excel VBA code to efficiently merge and sum duplicate values by taking into consideration columns A, B, and C together, with the result starting from column G? My current code, which I found on the internet, runs slowly and only processes column A, so I would like to incorporate the use of a dictionary and an array to speed it up, as I work with data that is likely to increase in size. Please output the answer from cell G2, noting the correspondence with column names. If VBA is not available, use the tools you have. Do not add any additional number formatting.
